T0 WHOM IT MAY CONCERN:

'Be it known that I, WILLIAM Bonner, of the city, county, and State of New York, have made certain improvements "in the Covers and Brushes for Mucilsge-Bottles and in order that others skilled may be enabled to understand the some, I give thefollowing description thereofi illustrated by the accompenying'drawings, and referred to in this schedule by the figures .and letters marked thereon.

i The object of my invention is to furnish a. means whereby, in a. cheap and simple manner, the brush in mucilage-bcttles moy'be kept constantly immersedin the liquid, to prevent the hardening of the brush and to. take up suflicient for ordinary use, and, by pressure on the handle, to take up a. greater quantity when this is needed, and whereby also this partial immersion of the brush may be maintained by slipping the handle down .word as the mucilage becomes lower in the bottle. In order to efi'ect this I enclose in a. tube attached to the ordinary cap a. spring nnd collar through which the handle of the brush passes, a hole of the size of the handle being made in the end of the tube and in the cap. The spring mey he a. metallic spiral or made of rubber; the collar may also be either of metal or rubber. When the spring is of rubber it should be a thin cylinder, or it may be slightly conical, and some space must be left between it and the tube in order that it may spring outword when the brush is pushed down. when the collar is of rubber it should be a short, thick cylinder, sprung on the handle tightly enough to press the-spring down, but still free enough to allow the handle to be moved in it with more pressure. When'mmstelcnllur is used it is a split ferrule sufficiently thick to abut against the end of the'spring, clnsping the handle strongly enough to hold it in place, but, like the rubber collar,'ollowing it to move when pressure, which overcomes the tension of the spring, is applied.

Desm'ptz'on of Drawings.

Figure 1 represents, n longitud a section, a muciloge-bottle with my invention attached. A A, the bottle; B B, the cap; C C, the tube; D, the rubber collar; E, the spring; F, the brush; G, handle; H', the muciloge.

Figure 2 represents at E a rubber spring, and at D a. metal collar.

Figure 3 shows a. mucilngebottle as it appears externally with my improvements; the-same letters refer to thc same parts as in fig. 1. i

I Mode of Operation.

I The brush is placed so that its point is in the mucilage just for enough totalcc up esmall quantity, suflicient say for sealing a. letter, and this amount of immersion also keeps the brush moist and pliant. When more is required, it is only neccssary to press the handle downward, and the coller pressing on the spring allows the brush tosink deeper into the fluid or mucilage. When the mucilage is used too low for the end of tho brush to be immersed in it, a pressure is given the brush suflicient to slip the handle it. little way through the collar, and so )011 till it is used up. On filling the bottle again the brush-handle is drawn upward through the collar;

I'am aware that o. screw turning in the cap has been used to raise and lower the brush, also a screw combined with a. spring, and an elastic cap of ljubberolso, nnd a'gnetal cover springing against the brush-handle, but none of these efl'cct theobject so simply and cheaply as my device, and Imuke no claim to them but what I do claim is--- I 1. The use of a spring collar orwasher on the handle of a. mucilage-brush.

' 2; The use of the some in combination with a spring and the cap of a. mucilege-bottlc.

3. The use of a tubular rubber spring in combination with a mucilage-bottle, all made and operating as described, or their mechanical equivalents.
